PHILADELPHIA, PENNSYLVANIA.

ENGINE-REGISTER.

SPECIFICATION forming part of Letters Patent No. 297,872, dated April29, 1884.

Application filed April 21, 1881. (No model.)

Tou/,ZZ whom it may concern.:

Be it known that I, FREDERICK W. TAT- TERSALL, of the city ofPhiladelphia, in the county of Philadelphia and State of Pennsylvania,have invented certain new and useful Improvements in Counters forEngine-Registers; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use thesame,reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

Figure 1 is a top view of my improved reg- Fig. 2 is a side elevation ofthe same. Fig. 3 is a diagram showing the peculiar interlocking of thedial-wheels when fixed and when changing, and the location of thedriving-tooth in the middle of the opening of the upper rim of thewheel.

The same letter indicates the same part wherever it occurs in thedrawings.

The obj ect of my invention is to simplify the construction of anengine-register invented by Cyrus Chambers, J r., for which anapplication for apatent is filed simultaneously with my presentapplication.

My improvements on that machine consist in dispensing with theindependent spurgears and driving-teeth, changing the manner ofinterlocking the flanged rims of the dial-wheels, locating thedriving-spurs inside the periph-l ery of the upper rims of thedial-wheels, and xing those wheels on vertical shafts, thus occupyingmuch less room and greatly economizing the cost of manufacture7 all ashereinafter more specifically set forth.

In carrying my improvements into practice I place ona series of parallelupright shafts aseries of dial-wheels like those used in Chamberssmachine, diagonally arranged relatively to the frame, and providedvwithfianged rims projecting both up and down from the bodyof the wheel, likethe flange of a pulley. Each rim has in its lower edge ten equidistantnotches or openings, and in its upper edge a larger opening divided byaninterposed driving-tooth. The upper edge of the flanged rim of eachwheel engages with two ofthe notches of the under edge of the wheel nexton its left, so as to interlock with said wheel at all times and preventit from moving until the opening o in front of the driving-tooth isbrought by revolution wheel to pass within the upper rim of thedriving-wheel at the moment the driving-tooth engages a notch on thelower rim of the driven wheel, and revolves it'a distance equal toonetenth of a revolution. The digits from l to 0 are marked on the facesof the flanges, and indicate through openings in a perforated dial (notshown) the movement of the wheels in a decimal series in the well-knownway, each wheel, by an entire revolution, moving the wheel on its leftone-tenth of a revolution, all

forth.

In the drawings, A marks the frame of the machine; B C D E F, a seriesof parallel vertical shafts turning inthe frame, and carrying a seriesof dial-wheels, G II I J II, provided with flanged rims having in theirupper edges, j", an opening, m m, divided by a tooth, t, and in theirlower edges ten equidistant notches, u n, as most clearly seen in Fig.3.

Of the flanged disk-wheels, G is the drivingwheel; II, the units-wheel,I, the wheel for tens5 J, that for hundreds,77 and K for thousands.77The ten digits from 1 to O are marked upon the faces of the severalwheels above the notches, as shown. 'Ihey are read, in the usualway,through a perforated face or dial. (Not shown.)

The operation is as follows: Shaft B receives rotation bymeans of anysuitable or convenient connection from the engine whose revolutions orstrokes it is designed to count and register. For every revolution ofthe engine the disk G makes one revolution. Its upper flanged rim, f, islocked in twoof the lower notches of the units-wheel H (in the mannershown by the broken wheel on the right hand of Fig. 3) until the openingm, passing under its rim, allows wheel H to turn one-tenth of arevolution under the impulse of tooth t on wheel G. Each revolution ofwheel G causes the wheel H to move one notch. Ten revolutions of wheel Gproduce one revolution of wheel II. The sameratio of movement and thesame mode of operation prevail throughout the entire series of wheels,to whatever into position to allow the notches of the driven in themanner hereinafter more specifically set`r IOO number it may beextended. Every movement is positive, the iianged rims are alwaysinterlocked, and every wheel is immovable until the movement becomesnecessary to indicate a change ot' count. The direction of movement ofcach wheel is indicated by the arrow upon it, and the order ot` thedigits upon each is arranged accordingly, so as to give the properreading at the dial at each revolution of the engine.

I disclaim any and all of the devices or meehanisms shown in Patent No.215,101, Reissue No. 9,118, and English 'Patent No. 1,957 of 1862.

My hcreinbel'ore-described invention is an in'iprovemcnt upon a certainengine register or counter invented by Cyrus Chambers, Jr., who iilcd anapplication tor Lett-ers Patent for his invention on or about the 13thday oi" April, 1881.

The improvement consists,simply,in removing a portion ot' the `[lange orrim ol" the interlocking-wheels ol" the said device of Cyrus Chambers,Jr., and inserting the propellingtooth tupon the wheels in the intervalbetween the ends of the ilanged part, whereby the tooth ot' one wheelserves to propel the adjacent wheel by ilnpinging against theprojections successively on the lower rim ol" the latter, as describedand hereinafter claimed.

In said device ot" Cyrus Chambers, J'r., the registeri iig-wheels aredriven by means ot'the coinbination ot' a toothed wheel fixed to theshaft of the registering-wheel with a tooth or spur which projects fromthe shalt ot' the preceding wheel, so as to engage with the teeth ol"the said toothed wheel successively.

Having thus described my invention, I wish it to be understood that I donot claim anything described and shown in English Iatent No. 1,957 of1862, United States Patents Nos. 215,101, 221,652, and Reissue No.9,118; but

'What I claim, and desire to secure by Letters Patent, is

In an engine-counter, a train of register or dial wheels, each providedwith adoubledlanged rim, one edge ot' which rim having a driving-toothin a slot or interval therein, and the other or opposite edge having aseries ot'notches therein,said train ot' wheels being constructed,combined, and arranged in successive relation to each other in themanner shown, and for the purposes described.

In testimony that I claim the foregoing as my own I altix my signaturein presence ol" two witnesses.

F. XV. TATTIGRSALL.
